Use brass golem to mine other cryptocurrencies

In few weeks or months we would have the release of brass golem, which will allow us to earn golem for the spare CPU/GPU cycles on our machines. This would imply that we will be able to avail a large amount of decentralised processing power. Could we put this to use for mining crypto currencies, profitably?

I imagine that there should be an app which would should purchase compute power at a price less than one could make by mining (the most profitable coin). If that doesn't become profitable, the app should simply switch to providing compute power to the golem network.

What are you thoughts on this? Do you know someone who can make this happen?
